As people live longer, finding ways of halting the decline in mental agility is becoming increasingly important, said Professor Ian Robertson, director of the Institute of Neuroscience at Trinity College Dublin.

"The biggest threat to being able to function well and properly is our brains," he told journalists at the British Association for the Advancement of Science meeting in Dublin.

"There is very strong evidence, particularly in the over-50s, that the degree to which you maintain your mental faculties depends on a handful of quite simple environmental factors," he said, having identified seven key areas.
